Editor's Pick: When your hands are full with groceries or you're carrying a child, the lock senses you and opens automatically—no need to free up a hand to press a fingerprint. The included M100 Hub connects the lock to your home's smart system, so even when you're away, you can see who entered and at what time. The two batteries last a long time, and your phone alerts you before they run out, so you never have to worry about being locked out.
